Anyone else totally annoyed by this article? I mean what was the point of this thing and how did it relate to the kernel? If the point was to show how a nifty Perl module can manipulate raw sockets then I could have done without all the 'Deep Fade' and '3G wideband code-division multiple access modulating channel model's and a whole lot more of why I should care as a Linux user/admin/enthusiast/developer.
